APPARATUS FOR TREATING VISCOUS ROCK FOR PAVING PURPOSES.

SPECIFICATION forming part of Letters Patent No. 447,711, dated March 3, 1891.

Application filed September 26, 1890. Serial No. 366,197. No model.)

To all whom it may concern.-

Be it known that I, ALBERT IV. HYDE, of Newton Centre, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Apparatus for Treating Viscous Rock for Paving Purposes, of which the followin g is a specification.

My invention relates to means for crushing or grinding bituminous and other viscous rock; and it consists of an improved apparatus, comprising in its construction a preliminary crusher, which may consist of a pair or pairs of jaws, or a pair of rollers for breaking the rock into fragments, a pair of rolls having corrugated or other suitably-formed surfaces, adjusted or gaged to grind or granulate the fragments received from the preliminary crusher, and a second set of rolls adjusted or gaged to pulverize or finish the I treatment of the material reeeived'from the first set of rolls, and suitable means for conveying the material from the preliminary crusher to the first set of rolls and from the first to the second set of rolls.

My invention also consists of combining with the foregoing devices a heater for heating the material after it comes from the finishing-rolls.

My invention also consists of parts and combinations of parts incidental to the foregoing, all as will more fully appear hereinafter.

Reference is to be had to the annexed drawings and to the letters of reference marked thereon, forming a part of this specification, the same letters designating the same parts orfeatures, as the case may be, wherever they for supplying the same with material, and the 'lfinishing-rolls and their supplying means.

Fig. 6 is a cross-sectional view of the heater and some of its adjuncts. Fi 7 1s an end view of the same. Fig. 8 is a side elevation of a modified form of apparatus. Fig. 9 is a vertical sectional view of another modification.

In carrying out my invention I employ a crushing device A, capable of breaking vis. cous or non-friable ro'cksuch, for instance, as bituminous rock or rock impregnated with mineral pitch.

In the drawings I have shown the device A as consisting of what is commonly known as a Blake crusher, a designating the fixed jaw, Z) the movable jaw, and o the toggle-levers for operating the movable jaw.

(Z is the eccentric shaft, by which, through the medium of the pitman f, the toggle-levers are operated.

g is the rubber spring, which operates on the rod it, connected with the movable jaw 11 to open the jaws.

The material is fed through the preliminary crusher A, being operated upon by the jaws to b to crush or break it into fragments, and is conducted by any suitable conveyer to a set of crushing or pulverizing devices B, consisting of a pair of rolls 1 j, having, preferably, corrugated surfaces and so arranged as that the ribs of one roll will operate in theflrooves of the opposing roll, as is shown in Figs. 3 and 4, the said rolls being so gaged or set as to grind or granulate the fragmentary rock, whence it is conveyed by suitable contrivances to' a set of finishing-rollers 7c Z, thesurfaees of which are corrugated, and if corrugated I prefer that the corrugations should be of finer gage than those of the granulating or grinding rolls 2 j. The rolls A; are so set or adjusted as to effect a practical pulverization of the granulated material.

In Fig. 5 Ihave shown an Archimedean screw m, as arranged to convey the pulverized material from the pulverizing-rollers Z to a heater consisting of a drum n, lined with a series of pipes o, to which steam, hot water, or hot air or other gas may be conveyed through the supply-pipe 1), provided with branch pipes q.

r designates leaves or strips of metal, c0nnected with the lining-pipes 0 and extending radially inward, which leaves serve as the heater is rotated to hold the material in one position for a longer time than would otherwise be the case in contact with the heated pipes and to as thoroughly stir the material in the heater as maybe necessary. The heater may be rotated by means of toothed wheels 8, 011 the ends of a shaft t, driven by means of a belt (not shown) on pulley a. The toothed wheels 3 may engage teeth 1;, formed in the periphery of the drum n, which latter device may rest upon wheels or rollers w.

Vhilc the heater is shown in Fig. 5 as arranged in horizontal position, it will be in practice arranged so that the receiving end will stand upon a higher plane than the opposite end, in order that the material fed thereto by the screw m may gravitate to the opposite end and be discharged therefrom. I have shown the heater as mounted upon wheels as, so that it can conveniently be moved into and out of place with respect to the conveyer m, it being understood that the heater is a part of the apparatus which may or may not be used, according as to whether it is desired to make immediate use of the productor to pack or store it for future use.

In Fig. 1 the preliminary crusher A, the granulating device B, and finishing or pulverizing device 0 are shown as arranged upon the same horizontal plane, and the conveying devices between the crusher A and granulating device B and between the latter and the pulverizing device 0 are shown as consisting of an endless line of buckets 3 which run over pulleys or sprocket-wheels In Fig. 8 the devices A, B, and O are shown as arranged on different floors of a structure, the one above the other, the conveying clevices consisting of chutes or pipes to b and hoppers c (1, while in Fig. 9 the several devices A B O are shown as supported in a single frame 6', the conveying devices consisting of hoppers and connected pipesj'" g h. The

crusher A is shown in Fig. 9 as consisting of a pair of rolls t" j, which may be supposed to be coarsely corrugated, and adjusted so as to affect the breaking of the rock into fragments. These various forms of construction and arrangement of devices are illustrated in order to show the changes which may be made in team my invention without departing from the nature or spirit thereof.

In Fig. 9 are shown scrapers or cleaningfingers 71;, pivoted at Z, with their operating ends resting against the face of the crushing, granulating, and finishing rolls, their opposite ends being weighted, as at m. These contrivances serve to clear or free the surfaces of the rolls from material which may have a tendency to adhere thereto.

My invention is specially designed for the treatment of mineral pitch-bearing rock, such as what is commonly known as bituminous roclt, which is employed for paving purposes, and which is of a quite non-friable viscous nature and difficult of pulverization. By first fragmentizing the rock, then granulating it, and finally pulverizing it I am enabled to get a thoroughly-efficient and uniformly-fine produet, which is not obtainable byother known means.

Having thus explained the nature of my invention and described a Way or ways in which the same may be used, I declare that what I claim is 1. In an apparatus for treating bituminous or other rock, the combination, witha preliminary crusher, an intermediate granulating device, and a pulverizer, of a heater and a conveyer to deliver the pulverized material to the heater, substantially as described.

2. In an apparatus for treating bituminous and other rock, the combination, with a preliminary crusher, an intermediate granulating device, and a pulverizer, of a heater, mechanism for revolving said heater, and mechanism for delivering the pulverized ma terial to the heater, substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 22d day of September, A. D. 1890.

ALBERT IV. HYDE.
